I've connected my Model 12 to my PC, and I'm using it as the default audio device in Windows. Sometimes when I play a game the audio starts behaving strangely. It's like it's distorting somewhat, but also almost sounds like playback is somehow "slowed down" or lagging? It sounds almost like a weird flanger effect. This seems to happen when the PC is working with relatively higher loads. I never had this issue when I plugged my headphones straight into the onboard audio device. Does anyone have a clue what gives? Thanks!
